Covering is made selectively with an insulating layer 26, and the element 14, the terminals 24 and the element 27 are connected by metal wires 28 and then sealed up by a sealing material 29. Subsequently, a permanent magnet 15 for impressing a bias magnetic field Hb is provided on the lower side of the metal plate 22 and sealed up integrally by a molding member 30, and these components are accommodated in a shield case 31 of a magnetic material. When a current (i) is made to flow from the left to the right of the metal plate 22, a magnetic field Hk is generated in parallel with the upper side of the base 12 and at a right angle to the surface of this paper. The magnetoelectric conversion element 14 given the bias magnetic field Hb intersecting the Hk perpendicularly by the magnet 15 detects the Hk and this is taken out from the terminal 24 through the amplifier circuit 27. This small-sized current detector can be mounted on a printed circuit board in the same way as various circuit elements.
